I recently asked for a restructure deal for my vehicle and standard bank said that i should wait for the current deal to expire for me to re negotiate then I tried numerous times to mail the lady that helped me and no response. I then get a mail saying my deal expired and i should now continue with the installment with only 2 days notice......please can i get some assistance standard bank assisted me with such professionalism with the last problem I really don't understand what went wrong.
